Bella DePaulo (Ph.D., Harvard), an expert on single life, is the author of books such as Singled Out: How Singles Are Stereotyped, Stigmatized, and Ignored, and Still Live Happily Ever After, and How We Live Now: Redefining Home and Family in the 21st Century. She also writes the “Living Single” blog for Psychology Today and the "Single at Heart" blog for PsychCentral.

Atlantic magazine has described Bella DePaulo as “America’s foremost thinker and writer on the single experience.” Dr. DePaulo has discussed single life on radio and television, including NPR and CNN, and her work has been described in the New York Times, the Washington Post, the Wall Street Journal, USA Today, Time, Atlantic, the Economist, the Week, More, the Nation, Business Week, AARP Magazine, Newsweek, New York magazine, and many other publications. Professor DePaulo has also written for the New York Times, Washington Post, the Guardian, Time magazine, Forbes, the Chronicle of Higher Education, Nautilus, Quartz, Alternet, Truthout, and other publications.

Dr. DePaulo’s 2016 standing-room-only invited address at the American Psychological Association, describing the rich lives of single people and their greater psychological growth than married people, “caused something of an internet earthquake.”

Professor DePaulo is an award-winning researcher with more than 100 scholarly publications. She has served in important leadership positions in her profession, and her research has been funded by groups such as the National Science Foundation and the National Institutes of Mental Health. She has lectured extensively in the U.S. and in other nations around the world. She recently gave a TEDx talk in Hasselt, Belgium.

Thanks to George Plimpton, she also got to play baseball in Yankee Stadium.
